mobilist may frequently, however, run out cf gasoline along the highway during the night time, and when he does run out of gasoline he occasions the owners of such gasoline stations considerable inconvenience in gettnig them out ofbed. My apparatus, it will be seen, obviates all of these nuisances 7 both to the owner of a gasoline station 311C to the automobilist.

An important object of the invention is to provide an apparatus of this nature which may be adjusted so as to dispense the proper amount of gasoline for the particular coin adapted to be received in the maratus, so that the varying prices of oline may be compensated for from time time. f Another very important object of the in ventien is to provide an apparatus having a structure wherein it is impossible for an nobilist to tinker with the same in such ianner as to obtain more gasoline'than he is entitled to in accordance with the coins deposited.

further very important object of the in\ ention is to provide an apparatus of this nature having an exceedingly simple constructien which may be manufactured at a comparat' ely low cost, one which is durab'le, reliable, and eflicient in operation, not likely to easily become out of order, easy to manipulate, readily adjustable, fool-proof,

and otherwise well adapted to the purpose which it is designed.

iii the above and numerous other ob in view as will appear as the descripproceeds, the invention resides in certain novel features of construction, and in the conciliation and arrangement of parts as will be hereinafter more fully described and claimed.

V In the drawing ratus embodying the features of my inven-' tion.

Figure 2 is an elevation with'the door removed showing the operating mechanism of the apparatus,

Figure 3 is a vertical section there through, v

Figure l is an enlarged detail view of the tank emptying valve, v

Figure 5 is an enlarged transverse section through the piston rod taken substantially on the line 55 of Figure 2, looking -downwardly;

Referring to the drawing in detail it will be seen that 5 designates a source of supply in the form of tank embedded in'fthe ground. such as is the commonpractice, and having associated therewith suitable apparatus for forcing the gasoline in the tank upwardly through the supply pipe 6. The

numeral 7 designates a casing having-a" hinged door 8, with suitable locking means 9 associated therewith. This casing forms a safe for the parts of the apparatus which should be non-accessible to the purchaser and the casing should be of such strength as to prevent unauthorized access to the interior thereof. This casing 7 is preferably located on the surface of the ground along the highway, above the supply tank 5. The supply pipe 6 rises through the bottom of the casing 75, and extends through the top thereof as is indicated at 6' in Figure 1', to deliver gasoline into a measi'iring display tank 10, pr ferably made of glass so that the gasoline collecting therein will be visible, and having the usual protecting means 11 thereabout. This tank 10 is mounted on top of the casing 7 by means of bracketslQ or in any other suitable manner.' Y

A valve 13 is located in the bottom portion of the supply pipe 6 within the casing .7, and will be hereinafter specifically designated as the primary valve. A. valve 14 "is provided in the pipe 6 intermediate the top and bottom of the casing 7 and will be referred to hereinafter as the secondary valve. A relatively short fulcrum bracket 15 rises from the bottom of the casing 7. A rocker bar 16 has its intermediate portion pivoted as at 17 in the upper end of the bra ket 15. One end of this rockerbar is operatively connected with the jvalve 1 3 by a link 13', and with the bottom end ofa rod 18, as is indicated at 19. A piston rod is indicated generally by the letter A and insite direction or away from the door 8.

in rocking the shaft by the eludes an upper section 20, and a lower section 21, the latter having indicia marked thereon for regulating the adjustment of one section in relation to the other, and also provided with a notch 23. frame 24: receives the overlapping portions of the sections and 21, and has a set screw 25 therein in order that these sections may be connected in different adjusted positions whereby the length of the piston rod may be varied for controlling the amount of gasoline which will be dispensed upon the operation of the apparatus as will be evident as the descrip tion proceeds. The section 20 extends through an opening 26 in the top of the cas ing 7, and through a stuiling box 27 in the bottom of the tank 10, and is connected to a piston 28 slidable within the tank 10.

,The section 21 is pivotally engaged at its 20 bottom end to the other end of the rocker bar 16 as is indicated at 29. A dog 30 is pivoted intermediate its ends as at 32 to the extremity of a bracket extending inwardly from one side of the casing 7 This dog 30 has its upper extremity normally heldby a spring 31 so to engage in the portion of the casing 7 and has formed thereon cranks 36, and 37, extending in one direction toward the door and a third crank 38 extending therefrom in an oppo- The rod 18 has a pin and slot connection, as indicated at 39, with the extremity of the first crank 36. A serond rod 5 .0 is pivotally en- 37, and 38 extending substantially horizonbeinp limited doe: 3O engaging intermediacy of tally therefrom, the s 'iring the section 21 through the the rod 11, and crank 37. When the parts are disposed as is shown in Figures 2 and 3, the valve 13 is closed, and the valve 1% is open.

The shaft 35 is adapted to be rocked by the crank 43 through the intermediate face of a suitable coin controlled nieihanism C of any well known type.

When the shaft 35 is oscillated manual throwing of the crank 43 throi the suitable coin controlled meehani, the following operations take place. As the shaft 35 rotates in a countcr-clockwise d rection, referring to Figure 3, it will be seen that crank 36 pulls on rod 18 to rock l. '1. snafu causes crank 37 to pullupon the rod 11 pull downwardly on the piston rod A and move the piston 28 a distance downwardly in the tank 10. As the shaft 35 moves in a clockwise direction. still referring to Figure 3 and release the (log 30 from the notch 23 (it will be understood that the lost motion connection afforded by the pin and slot connection 39 allows the dog 30 to release from the notch '23 before the rod 18 is actually actuated), and the second movement of the shaft, with the aid of spring 31, returns the dog 30 to an engaging position with the notch 23, but of course, not engaged therewith since the notch has moved downwardly he-zause of the downward movement of the piston rod by the first movement of the shaft 35 as previously indicated. Thus, the gasoline is free to flow through the pipe 6 up into the tank 10. As the level of the gasoline rises it engages the piston 28, and moves the same upwardly. The upward movement of this piston pulls upwardly on the piston rod A, rocking the shaft 16 to close the valve 13, and pulling on the rod 18. The proper amount of gasoline should now be in the tank 10. The amount of this gasoline in the tank may be varied in accordance with the price of gasoline at the time of the operation of the apparatus by proper adjustment of the section 20 in relation to section 21, as heretofore indicated, the indicia provided on section 21 being there for this purpose.

An emptying pipe 59 leads from the bottom of the tank 10 through the top of the casing 7, at 60, and out through the side of the casing at 61. A valve 62 is provided in the pipe 59 within the casin 63 is provided in the pipe 59 exteriorly of the casing adjacent the end to which is attached the filling hose 642. A red 65 is ,operatively connected with the valve 62,

and pivotally connected as at 66 to the rocker 16, adjacent the end 29 so that when the bar 16 is rocked to pull downwardly on the piston rod A, said rod 65 closes the valve 62 and'when the bar 16 is rocked to push upwardly on the piston rod, the rod 65 opens the valve 62. The valve 63 has a novel structure, and particu lar attention is now called thereto. A V- shaped passage 67 extends longitudinally through the valve body and is bisected by an opening 68 for slidably receiving the valve plate 69 which is provided with a pass 70 at its lower end. The upper end of the valve plate 69 terminates above the valve and a valve 1 eenaw body. 63,. A bracket. 71; rises from the valve body 63., and has. pivotally mounted on. its upper end as at 72 av lever 78,. which is pivotally engaged. adjacent one end as at 7.4 with the upper end of the plate 69; The end. of the lever 63 isv pivotal-Ly engaged as at T5 with the upper end 0 1"". the rod 7 (3- looped as at 77 to extend about the pipe 59. The rod" 76 extends into the casing 7, as at8 and terminates in a transversely disposed loop 79. An auxiliary rod 80 has a looped lower extremity 81 disposed about the; bar 16,. adjacent the point 66, while its upper end is formed with a transverse loop 82, adapted to receive; the rod 76, the loop 79. being aiil-a-pted to receive the rod 80; A spring 831-is disposed between, the loops 79 and 82 to normally hold them separated a predetermined distance.

Supposing the, tank 10 to have been; filled with the proper amount of gasoline as heretoiiore described, the automobilist. places the hose 64 with the nozzle Stthereof in the gasoline tank of the automobile, and then depresses the handle portion 85 of. the lever 7.3. The initial movement of this leverpartial-ly raises the plate 69,.but does not bring the passage 70 in. registry with the passage 6-7,, but raises the rod.- 76 so'that the spring 83 raises the rod 80 until the bar 16 is rocked, it this has not been done in the manner heretofore indicated, so as to insure the closing of the valve 18, and the engagement of the dog, 80 with the notch 23. The further movement of the lever merety compresses the spring 83 and: continues to] litt the valve plate 69' so as to bring the passage 70 into registry. with the passage 6:7, so that the gasoline may flow by gravity irons.v the tank 10 through; the pipe; and hose 6.4: into the fuel tank of the. automobile. The; valve 68, and the associated: mechanism prevent the autom'obilist from obtaining more gasoline than; he isentitled to, since; soon; as heopens the; valve; 63, the: appavratus in; the casing 70 is operated to close the valve 13, and prevent any more gases linefrom flowing up. into the. tank. In actual, practice, using a coin control mechanism; adapted to receive a. sitver dollar and to; maintain the. piston; rod A. in adjust ment so that one doll'ars worth of" gasoline will be delivered to the tank 10, It is ob-'- vious, of course, that any other suitable coin tormtherewith. The piston; rodA. of course,

is further adjustable; to compensate for; the varying price in gasoline so that the purchaser will. always obtain a dollars worthregardless oi the current: price of the gasoline.

It will be seenthat the apparatus is comparatively simple in its construction, is easy to manipulate both "from. the standpoint of the owner and the. purchaser, is thoroughly reliable and eflicient, is fool-proof, is Well adapted to; the dispensing: of; gasoline by a coin control mechanism, and the manual operation of a purchaser.

The present embodiment oi the invention has been disclosed detail merely by Way of example because actual practice it at tains the. featuresof: advantageenumerated as desirable in the statement of the invention, and the above description. It ,will' be apparent that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted"v to without (ileparting from the spirit or scope ot the invention as hereinafter claimed orsacrificing any of its; advantages.
